An offline Wi-Fi Protected Setup brute-force utility

Pixiewps is a tool written in C used to bruteforce offline the WPS PIN exploiting the low or non-existing entropy of some Access Points, the so-called "pixie-dust attack" discovered by Dominique Bongard in summer 2014. It is meant for educational purposes only.
As opposed to the traditional online brute-force attack, implemented in tools like Reaver or Bully which aim to recover the pin in a few hours, this method can get the PIN in only a matter of milliseconds to minutes, depending on the target, if vulnerable.
